Abstract: Methods and apparatus for automating the orientation of a selected mirror mounted on a vehicle. The apparatus comprises location apparatus for sensing the location of the driver's eyes, a computer controller, and a mirror positioning mechanism. The location apparatus may comprise various types of distance sensors and orientation detectors. The controller determines the desired orientation of the selected mirror based upon the position of the driver's eyes, known vehicle parameters and vision parameters, and generates control signals. The mirror positioning mechanism receives the control signals and positions the mirror in response thereto. The subject method includes the steps of determining the coordinates of the eyes of an individual using the mirror, determining the desired orientation of the mirror based upon these coordinates and the center point of the mirror and the reflected sightline vector, and then adjusting the orientation of one or more selected mirrors to enable the individual to see a pre-selected reflected sightline.

The shaft has a grooved, outwardly facing circumferential sidewall portion positioned within the body toward the body second end and a smooth, outwardly facing circumferential sidewall portion positioned within the body between the end flange and the shaft groove sidewall portion. The end flange extends laterally outward beyond the shaft smooth sidewall portion and the shaft grooved sidewall portion has an outer diameter equal to or less than the outer diameter of the shaft smooth sidewall portion. The shaft grooved sidewall portion is formed as an integral part of the shaft, and the end flange as an integral unit with the shaft. The actuator further includes an annular piston sleeve positioned within the body and having a central aperture receiving the shaft therethrough. The piston sleeve is mounted for reciprocal axial movement within the body in response to selective application of pressurized fluid to a piston portion thereof in sliding sealed engagement with the shaft and body smooth sidewall portions to define fluid compartments to each side thereof. The sleeve portion has a grooved, inwardly facing circumferential sidewall portion engaging the shaft grooved sidewall portion, and a grooved, outwardly facing circumferential sidewall portion engaging the body grooved sidewall portion as the piston sleeve reciprocally moves within the body to translate axial movement of the piston sleeve into rotation of the drive member.

Abstract: An all terrain vehicle in one embodiment provides greatly improved traction. The vehicle includes a grooved rear wheel, a suspension system, and a cleated track with an endless ridge on the driven surface of the track. The ridge cooperates with the groove to align the track on the wheel. During forward propulsion, the track passes under the rear tire then rearward under two bogeys, then around an idler assembly and back over a third bogey back to the wheel. On level around, the suspension system locates the bogeys and the idler so that the idler guides the track away from the ground. Each bogey aligns the ridge in a gap between tapered surfaces. Tapered surfaces remove debris from the driven surface of the track. The idler aligns the ridge between pan shaped rims. The suspension system includes a swing arm hitch and a shock absorber. The swing arm pivot is located behind and below the rear axle toallow movement of the idler assembly in a wide vertical arc for forward and rearward propulsion over uneven terrain.
